IMPROVEMENT `IN GAS-REGULATORS.

Specification forming part of Letters Patent No. 146,661, dated January20, 1374; application tiled December 9, 1873.

lo all whom it may concern:

Beit known-that I, JAMES S. DE IALos, oi' Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin GasRegulators, of which the following is a speciiication:

My invention relates to certain improvements in gas-regulators to beattached to gasmeters; and it consists in a cylindrical casting dividedby a longitudinal partition into two parts, the lower part to beattached to the outlet of the meter, and the upper part to be attachedto the service-pipe, the inner end of the casting being attached by ascrewthread to the regulator. 1- My invention consists further in theconstruction of the diaphragm with one or more thicknesses or layers ofductile metal, to render the diaphragm im' pervious to gas.

In the accompanying drawings, Figure 1 is a plan view. Fig. 2 is alongitudinal vertical section. Fig. 3 is a transverse vertical section.

A represents a cylindrical casting, divided by a longitudinal partition,c, into two compartments, B1 B2. The lower compartment B1 forms aninlet-tube having an inlet-opening, b1, on its under side provided witha screw-thread for attachment to the outlet-pipe of a gas-me ter. Theupper compartment B2 forms an outlet-tube having an outlet-opening, b2,on its upper side, provided with a screw-thread for The outer end of thecylinder A is closed, and the inner end is open and provided with' ascrew-thread 4for attachment to the regulator, which consists of aspherical case made in two sections, (ll C2, each section being providedwith a flange, c, for uniting them together by means of screws d. Thelower section Cll is divided by means of a partition, c, into aninlet-chamber, F, an outlet-chamber, G, and a drip-chamber, H, the

-, outlet-chamber being above the inlet-cham ber, and the drip-chamberbeing at one side. On the side of the regulator opposite thedrip-chamber is an opening, 17, provided with a screw-thread forattachment of the cylinder A. The partition cis in a vertical posi `myinvention I hereunto affix my signature.

tion between the drip-chamber, and in a horizontal position between theinlet and outlet chambers. About midway between the top and bottom ofthe regulator is a diaphragm, J, composed of two thicknesses of ductileor I may use a single layer of metal with one of leather. This diaphragmis secured 1n placeV b"`y having its periphery clamped betweentheflanges c c, when the sections Cl C2 are united together. In the centerof the diaphragm is secured the stem k of a valve, K. The valve` seat lis arrc nged in the upper part of the par-A tition c.

In the top of the regulator is an opening covered by ascrew-cap, M. Inthe center of this cap is a vent-hole, m.` The drip-chamber II has adischarge-orifice, Il., near the lower cerner, which orifice is providedwith a screwthread for the reception of a cap or plug. The cylinder A isattached to the spherical case Cl C2 by means of the screw-threads,andthe apparatus is attached to the gas-meter by the inlet-opening b1, andthe outlet-opening I;2 is attached to the service-pipe.

The object in disconnecting the cylinder A from the spherical case is toenable the manufacturer to make the cylinder with diierent sizes ofinlet and outlet openings to answer the purposes of a greater or lessdemand for gas, while but one size of regulator is used.

Having thus described my invention, what I claim as new, and desire tosecure by Let;

ters Patent, is-

1. The detachable cylinder A, provided with l "il" a partition, a,abutting against partition e, and an inlet and outlet, b1 and b2,substantially as shown and described. v

2. The draphragm J consisting of a layer or thickness of leather betweentwo continuous layers or thicknesses of ductile metal, the metal beingco-extensive with the leather, substantially as shown and described.

In testimony that I claiml the foregoing as JAMES S. DE PALOS.
